The document discusses how intentionally crashing systems or applications can make them more resilient. It draws an analogy to how car manufacturers crash test cars to improve safety. The document suggests that tools like monitoring, auto-scaling, auto-healing, and collaboration help applications withstand crashes like increased traffic, failures, and security issues, just as crash tests and safety features help improve vehicles. These tools are provided by companies like Scalr to design, manage, and govern resilient infrastructure and applications.
